Convert PDF to DXF via C#, .NET Core
Export PDF to DXF within .NET applications without using Adobe® Acrobat Reader or any other third party applications
Why Convert PDF to DXF format?
Converting PDF files to DXF (Drawing Exchange Format) format using .NET can offer several advantages. Firstly, DXF is a widely supported format in the CAD (Computer-Aided Design) industry, making it compatible with various CAD software applications. By converting PDF to DXF, you can easily extract and preserve vector-based drawing elements, such as lines, curves, and text, which can be further edited and modified in CAD software. This conversion allows for seamless integration of PDF-based designs or drawings into CAD workflows, facilitating collaboration and interoperability between different design tools. Additionally, converting PDF to DXF enables accurate scaling and measurements, ensuring that the transferred drawings maintain their precision and accuracy.

Convert PDF to DXF in a Single File via C#
Using the API, you can also convert PDF file to DXF to a single image file. In order to convert all pages, you can first render your PDF document to one TIFF file and after that you can export TIFF file to DXF. You can open the input file using Document class and create Resolution, TiffSettings, & TIFF device objects. You can get a single TIFF image using Process method of TiffDevice class. Finally, you can load TIFF file using Image class and save it to DXF format using Save method.
| // supports PDF, CGM, EPUB, TeX, PCL, PS, XPS, MD, MHTML, XSLFO, HTML file formats | |
| // Open PDF document | |
| Document pdfDocument = new Document("input.pdf"); | |
| // Create Resolution object | |
| Resolution resolution = new Resolution(300); | |
| // Create TiffSettings object | |
| TiffSettings tiffSettings = new TiffSettings | |
| { | |
| Compression = CompressionType.None, | |
| Depth = ColorDepth.Default, | |
| Shape = ShapeType.Landscape, | |
| SkipBlankPages = false | |
| }; | |
| // Create TIFF device | |
| TiffDevice tiffDevice = new TiffDevice(resolution, tiffSettings); | |
| // Convert a particular page and save the image to stream | |
| tiffDevice.Process("output.tif"); | |
| // load TIFF file | |
| var image = Image.Load("output.tif"); | |
| // supports Dicom, Jpeg2000, Apng, Psd, Dxf, Wmf, Emz, Wmz, Tga, Svgz file formats | |
| // save TIFF to PSD file format | |
| image.Save("output.psd", new PsdOptions()); |
Export PDF to DXF with Watermark via C#
Using the API, you can also convert PDF file to DXF with watermark in your DXF document. In order to add a watermark, you can first render your PDF document to JPEG and add a watermark in it. To demonstrate the operation, you can load your converted JPEG image, add transformations using an object of Matrix class and draw a string as the watermark on the image surface using the Graphics class’ DrawString method. After adding the watermark in it, you can save the JPEG as DXF format. Below is a code example that demonstrates how to add a diagonal watermark to your document.
| // supports PDF, CGM, EPUB, TeX, PCL, PS, XPS, MD, MHTML, XSLFO, HTML file formats | |
| // load PDF with an instance of Document | |
| var document = new Document("input.pdf"); | |
| // create an object of jpegDevice | |
| var renderer = new JpegDevice(); | |
| // convert a particular page and save the image in JPEG format | |
| renderer.Process(document.Pages[1], "output.jpeg"); | |
| // load an existing JPEG image | |
| Image image = Image.Load("output.jpeg"); | |
| // declare a String object with Watermark Text | |
| string theString = "45 Degree Rotated Text"; | |
| // create and initialize an instance of Graphics class and Initialize an object of SizeF to store image Size | |
| Graphics graphics = new Graphics(image); | |
| SizeF sz = graphics.Image.Size; | |
| // create an instance of Font, initialize it with Font Face, Size and Style | |
| Font font = new Font("Times New Roman", 20, FontStyle.Bold); | |
| // create an instance of SolidBrush and set its various properties | |
| SolidBrush brush = new SolidBrush(); | |
| brush.Color = Color.Red; | |
| brush.Opacity = 0; | |
| // initialize an object of StringFormat class and set its various properties | |
| StringFormat format = new StringFormat(); | |
| format.Alignment = StringAlignment.Center; | |
| format.FormatFlags = StringFormatFlags.MeasureTrailingSpaces; | |
| // create an object of Matrix class for transformation | |
| Matrix matrix = new Matrix(); | |
| // first a translation then a rotation | |
| matrix.Translate(sz.Width / 2, sz.Height / 2); | |
| matrix.Rotate(-45.0f); | |
| // set the Transformation through Matrix | |
| graphics.Transform = matrix; | |
| // draw the string on Image Save output to disk | |
| graphics.DrawString(theString, font, brush, 0, 0, format); | |
| // supports Dicom, Jpeg2000, Apng, Psd, Dxf, Wmf, Emz, Wmz, Tga, Svgz file formats | |
| // save JPEG to PSD file format with watermark in it | |
| image.Save("output.psd", new PsdOptions()); |
Convert & Rotate PDF to DXF via C#
Using the API, you can also rotate the output DXF image as per your needs. The Image.RotateFlip method can be used to rotate the image by 90/180/270-degrees and flip the image horizontally or vertically. You can specify the type of rotation and flip to apply to the image. In order to rotate and flip the image you can load the converted JPEG image using the factory method exposed by Image class and call the Image.RotateFlip method while specifying the appropriate RotateFlipType .
| // supports PDF, CGM, EPUB, TeX, PCL, PS, XPS, MD, MHTML, XSLFO, HTML file formats | |
| // load PDF with an instance of Document | |
| var document = new Document("input.pdf"); | |
| // create an object of jpegDevice | |
| var renderer = new JpegDevice(); | |
| // convert a particular page and save the image in JPEG format | |
| renderer.Process(document.Pages[1], "output.jpeg"); | |
| // load JPEG file | |
| var image = Image.Load("output.jpeg"); | |
| // rotate the image | |
| image.RotateFlip(RotateFlipType.Rotate270FlipNone); | |
| // supports Dicom, Jpeg2000, Apng, Psd, Dxf, Wmf, Emz, Wmz, Tga, Svgz file formats | |
| // save JPEG to PSD file format | |
| image.Save("output.psd", new PsdOptions()); |
Transforming PDF File to DXF Programmatically : Use Cases
PDF (Portable Document Format) files are used to store document information, making them ideal for creating static documents and publications. However, when working with detailed drawings and designs, DXF (Drawing Exchange Format) becomes essential for accurate representation and manipulation.
The conversion of PDF files into DXF formats is necessary to unlock the full potential of your design capabilities. This conversion enables you to:
Use Cases:

- Product Manufacturing and Prototyping: Use DXF to generate 2D and 3D models from existing designs, facilitating the creation of prototypes, molds, and tooling.
- CADCAM (Computer-Aided Design/Computer-Aided Manufacturing): Convert PDF files to create precise digital models for CNC machining, fabrication, and assembly.
- Geospatial Data Conversion: Use DXF to convert PDF files containing geospatial data into a format that can be used with GIS software, enabling detailed mapping and analysis.
- Automotive and Aerospace Design: Convert PDF files to generate 2D and 3D models from existing designs, facilitating the creation of prototypes, tooling, and manufacturing plans.
